Intervention Apparatus for Image Signal Format Conversion and Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing image systems, the different formats of image signals generated by various apparatuses lead to inefficient utilization and difficult joint control of display apparatuses, making it challenging to determine which display apparatus is connected to which image signal generating apparatus.
Innovation Solution
The introduction of intervention apparatuses that convert image signals from different formats to a standard format, such as HDMI with TMDS encoding, and add identification information, allowing for efficient utilization and easy joint control of display apparatuses, as well as facilitating the determination of connected apparatuses through user input and communication units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image signals from multiple apparatuses with different formats are directly connected to display apparatuses, then each display apparatus must support multiple formats, but this leads to inefficient utilization and difficult joint control of display apparatuses
Solution Approach 1:
The patent introduces an intervention apparatus as an intermediary component between image signal generating apparatuses and display apparatuses. This intervention apparatus converts image signals from various formats into a unified first format, allowing display apparatuses to maintain a single, standardized interface while still being able to display content from multiple source devices. This resolves the contradiction by centralizing format conversion functionality rather than requiring each display apparatus to handle multiple formats internally.
2Device complexity
If image signals are converted to a same format, then display apparatuses can be standardized and efficiently utilized, but it becomes difficult to determine which image signal generating apparatus is connected to which display apparatus
Solution Approach 1:
The intervention apparatus performs preliminary action by adding identification information to the image signals during the format conversion process. Before the signals reach the display apparatus, the intervention apparatus has already embedded metadata that identifies the source apparatus. This allows the display apparatus to receive standardized signals while still having access to identification information about which generating apparatus produced the signal, thus preventing information loss during standardization.
3Adaptability or versatility
If multiple types of display apparatuses are used to accommodate different image signal formats, then all formats can be displayed, but the display apparatuses cannot be jointly controlled efficiently
Solution Approach 1:
The patent implements universality by having the intervention apparatus serve multiple functions: it performs format conversion from various input formats to a unified first format, adds identification information, and outputs standardized signals compatible with a single type of display apparatus. This multi-functional intervention apparatus replaces the need for multiple specialized display apparatuses, allowing all display devices to be of the same type and thus easily controllable through unified control mechanisms.

AI summary
An image system includes image signal generating apparatuses; display apparatuses; and intervention apparatuses. The intervention apparatuses are interconnected between the image signal generating apparatuses and the display apparatuses, convert the image signals from the image signal generating apparatuses to image signals of a first format, add identification information regarding the image signal generating apparatuses to the image signals of the first format, and output the image signals of the first format and the identification information, respectively.
